And how will the US Economy fail with some positions working from home? Speaking from a software development perspective, I had dozens of interviews in the last few months from all states. ALL of their code and CI/CD pipelines are mixed between GitHub/TeamCity or Azure DevOps. So code and sprint planning/tracking and all of those things can be done remotely. All the way up to deploying to production with CI/CD. Nobody I talked to had on-premise work, and if they did there is VPN for that. I am sure Apple and Microsoft operating system code are on premise, but that is what VPN is for.
There are tools out there to generate monthly report on how much code is checked in, any code smells/issues tied to it, how much burn and stuff needs re-doing per check in, how much time is spent per story. If you manage software developers correctly, it can be done remotely. While some businesses I talked to, these stats are "cool" to look at, you can get down to the micro management level even remotely with these kinds of stats. You are not checking in code enough, or you are re-doing your work 10 times, you spent all day and checked in 5 lines of code for example.
